Abstract
The invention discloses an integral transmission box of an electric door. A torsion clutch is arranged between a power system of the electric door and an opening and closing device of the electric door; and therefore, when a closing operation of the electric door is blocked, torsion moment on a transmission shaft is increased till the torsion clutch is tripped, the electric door keeps at a state of harmful clamping force, a motor can not be blocked and burned up, and at the same time, the integral transmission box is matched with a control circuit to control the motor to reversely rotate, so that the electric door is opened. The integral transmission box is a mechanical anti-clamping device and has the advantages of simple structure, low cost, low failure rate, and safety and reliability. Simultaneously, a planetary gear is integrally arranged in a same transmission box body so as to integrate a speed reduction function, and thus the whole transmission box has the advantages of simple structure, light weight, small volume and the like.

Described planetary pinion and torsion clutch 14 are all installed in described transmission case body 9.
Described torsion clutch 14 comprises power input shaft 22, pto＝power take-off 27, moment of torsion output slide block 26, spring 24, connects ball 25 and supporting base 23;
Described power input shaft 22 one end and described driven axle 6 are in transmission connection;
Described power input shaft 22 is arranged with described supporting base 23, spring 24, moment of torsion output slide block 26 and pto＝power take-off 27 successively from described driven axle 6 side to opposite side; Described supporting base 23 is fixedly connected on described power input shaft 22, and described moment of torsion exports slide block 26 and pto＝power take-off 27 flip sleeve is located on described power input shaft 22;
Described moment of torsion exports slide block 26 and described power input shaft 22 is provided with the helical groove mutually mated, and is embedded with described connection ball 25 in described helical groove;
The one side that described moment of torsion output slide block 26 and pto＝power take-off 27 contact with each other is equipped with projection 29;
One end away from described moment of torsion output slide block 26 and the described start-stop device 8 of described pto＝power take-off 27 are in transmission connection.
The surface of contact of described power door operation at closing time between described projection 29 is processed with circular arc chamfering.
Its working principle is, during enabling, start power system 1, drive sun gear 12 to rotate, sun gear 12 drives planet wheel 11 to rotate around sun gear 12, and planet wheel 11 drives planet carrier 13 to rotate, planet carrier 13 drives driving shaft 3 to rotate, driving shaft 3 drives torsion clutch 14 to rotate, and torsion clutch 14 driving electric door operating gear 8 moves, and power door operation start-stop device 8 driving electric door is opened fast.Otherwise at closing time, power system 1 is reversed, planetary pinion reverses, and drive torsion clutch 14 to rotate, torsion clutch 14 driving electric door operating gear 8 cuts out power door operation.Wherein, the working principle of torsion clutch 14 is, during state of rest, moment of torsion exports slide block 26 under the effect of spring 24, being in moment of torsion exports on station, now, connects ball 25 and is in bolt indentation near supporting base 23 side, moment of torsion exports slide block 26 and intersects nested with the projection 29 of pto＝power take-off 27, now moment of torsion export slide block 26 and pto＝power take-off 27 due to projection 29 existence can together with rotate.When power door operation starts closing switch, power system 1 drives power input shaft 22 to rotate by driving driven axle 6, owing to connecting the effect of ball 25 and spring 24, moment of torsion exports slide block 26 and follows rotation, under the effect of projection 29, pto＝power take-off 27 rotates and drives start-stop device 8 to operate, power door operation is closed, until closing process terminates, if met with obstruction in closing process, the resistance that power door operation runs into is reverse passes to pto＝power take-off 27 and moment of torsion output slide block 26, when resistance is enough large, overcome the pressure of spring 24, force moment of torsion to export slide block 26, with pto＝power take-off 22, relative movement occurs, under the effect connecting ball 25 and helical groove, moment of torsion exports slide block 26 and moves to supporting base 23 side, connect ball 5 and be finally in helical groove near pto＝power take-off 7 side, now, the projection 29 that moment of torsion exports slide block 26 and pto＝power take-off 27 departs from mutually, the action of power door operation phase down, and power system 1 is with dynamic torque output slide block 26 to be rotated further, when projection 29 turns to nested position, under the effect of spring 24, moment of torsion exports slide block 26 and retracts original position, if now obstacle is removed, then power door operation has continued closing motion, if obstacle is not removed, then the projection 29 of moment of torsion output slide block 26 and pto＝power take-off 27 mutually departs under the effect of resistance, go round and begin again, until resistance disappears.
The beneficial effect of employing the technical program is: between the power system and the start-stop device of described power door operation of described power door operation, be provided with torsion clutch, make power door operation when closing hindered lift-cabin door, moment of torsion on transmission shaft increases, and finally make torsion clutch thread off, power door operation maintains harmless chucking power, and motor can not burn by stall, now coordinate control circuit to control motor reversal to open the door, this device is mechanical type anti-pinch device, and structure is simple, cost is low, rate of fault and safe and reliable.Simultaneously in same transmission case body, load planetary pinion in the lump, be integrated with the function of deceleration, make whole transmission case have structure simple, lightweight, the advantages such as volume is little.
